Isolating Gaskets

EVOLUTION™, the best available technology for pipeline isolation, incorporates all of these benefits into one complete and robust package.

 

EVOLUTION™ is a patent-pending product that is the first of its kind to be a fully encapsulated isolating gasket. The thinner, ⅛” (3mm) design minimizes the difficulties often encountered
while attempting to install thicker isolating gaskets. The total encapsulation allows the gasket to be hydro-tested and kept in the pipeline with virtually no loss in isolation properties. The coating is a GPT proprietary material that is extremely abrasion and impact resistant. The coating is also chemically resistant to attack by H 2S, steam, CO, CO 2 and other chemicals often found in oil and gas pipelines.

 

EVOLUTION™ has passed API 6FB fire testing in multiple sizes and pressures and has a considerable increase in operating temperature over GRE products. It also has a number of other advantages over traditional GRE laminated products. Since EVOLUTION™ has no laminations; it’s able to withstand high pressures with no ill effects unlike GRE gaskets, which are prone to de-lamination. Furthermore, EVOLUTION™ does not have the permeation issues that plague GRE gaskets.

 

ID Seal

  • Chemical resistance - remarkable resistance to typical oil and gas chemicals, in particular H2S, CO & CO2

  • Isolates after hydro-testing - eliminates the need to replace the gaskets following hydro-testing, EVOLUTION™ will isolate after hydro-testing

 

Fully Encapsulated (⅛” (3mm) Retainer)

  • No permeation - the unique design results in no permeation, a problem that plagues conventional glass reinforced epoxy (GRE) isolations gaskets

  • Easy installation - thinner design (⅛” (3mm)), minimizing the difficulties often encountered when attempting to install thicker isolating gaskets

 

Proprietary Coating

  • High dielectric strength

  • Eliminates exotic cores - fully encapsulated coating prevents the need for expensive exotic cores

  • High temperature - rated to 500°F/260°C*s

 

Inconel C-ring

  • Fire safe - provides the added security of knowing that the gasket has passed the API 6FB, 3rd Edition Fire Test

  • Eliminates exotic cores - fully encapsulated coating prevents the need for expensive exotic cores

  • High pressure - highest pressure rating of any isolating gasket
